Watch the full session: Denodo DataFest 2016 sessions: https://goo.gl/ptQMW7 What matters the most for analysts and decision makers is finding the right data within seconds. Data virtualization incorporates a rich metadata catalog and graphical interface for the self-service users In this session, you will learn: • How to discover, search, explore, curate and share trusted data assets in a governed manner • How to view and utilize the complete lineage of data assets • Ways to infer patterns in data and metadata This session is part of the Denodo DataFest 2016 event.

2. Metadata and Data: Search & Exploration
Pablo Álvarez Yáñez
Principal Engineer, Denodo

3. Search and Find the Right Data
3

4. - IDC, The high cost of non finding information
Knowledge workers spend from 15% to 35% of their time
searching for information.
Searchers are successful in finding what they seek 50% of
the time

5. Different Scenarios
5
“I know the data
model and I’m
fluent in SQL”
“I know my data
but I don’t want
to re-build a query”
“Do we even have
that data?”

6. Different Paradigms
6
SQL Query:
SELECT * FROM
Customer WHERE
City = ‘Palo Alto’
Catalog search:
What views/reports
do we have about
customers?
Keyword search:
Do we have data
about “Palo Alto”?

7. How?: SQL tools

8. How?: Catalogs

9. How?: Google (Indexes + Search Engine + Hyperlinks)

10. How?: Data Virtualization?
• DV is a central repository to access all
your data
• DV abstracts the underlying technology
of the data sources
• DV enables the definition of a semantic
data model
• DV offers a metadata-rich catalog
• DV offers multiple access methods:
• SQL based
• Keyword based search (using an index)
• RESTful navigation (hyperlinks)

VIRTUAL DATA MODEL

impact for our organization”

• Increase reusability and improves consistency
• Google-like keyword based search
• Allows end users to search for data without understanding the underlying data model
• Built-in query builder
• Supports personalization of filters, aggregations, projections, etc.
• Links to related data
• Enables complex drill-down and jump across different sources
• Integrated security model
• Role based security applied to all access methods

20. “Citizen Integrators”
Denodo’s Information Self Service tool allows non-technical end
users to access data within proper guardrails
• Secured
• Fine-grained RBAC to protect confidential data
• Data is consistent and trustworthy
• Encourage use of “certified data models”
• Controlled
• Denodo Resource Manager used to set plans and rules to protect resources
and ensure SLAs

23. Best Practices
• Document your views
• It really helps end users
• Create associations between views
• Makes discovery much easier
• Don’t include fact tables in your crawling/indexing
• They only have numbers and are not useful for keyword-based searches
• Set up proper guardrails
• Security
• Resource manager
